ModelExtrasTrait

saveAssociated

saveAssociated method is a wrapper method, that allows to save BelongsToMany and HasMany related models in a single transaction, e.g. suppose we need to save a product with its related categories, we would use

Product::saveAssociated($data, ['associated' => 'categories']);

the $data should be an array like this

$data = ['name', 'price', 'categories_ids' => [1, 3, 7]]
